[Dovecot] Dovecot Expire doesn't work
Hello,
I'm using dovecot and I want to use the "expire" plugin. However, it doesn't work, i.e. mails do not get deleted.
I ran /usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test
and besides printing
Info: stef/Trash: no messages left Info: stef/Spam: no messages left
it doesn't do anything (especially not deleting e-mails). Obviously, in stef/Trash and stef/Spam, there are e-mails waiting to be deleted.
I'm using dbox as mail storage; and use dbox:/var/mail/%u as mail_location in dovecot.conf. Furthermore, I'm running 1.1.16 on a gentoo PPC system.
This is the output from dovecot -n
1.1.16: /etc/dovecot/dovecot.conf
OS: Linux 2.6.29-gentoo-r2 ppc Gentoo Base System release 1.12.11.1 xfs
listen: *, [::] ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login verbose_proctitle: yes mail_privileged_group: mail mail_location: dbox:/var/mail/%u mail_plugins: expire auth default: verbose: yes debug: yes passdb: driver: pam args: * userdb: driver: passwd socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: fs:Disk Quota expire: Trash 7 Spam 30 expire_dict: proxy::expire dict: expire: db:/var/lib/dovecot/expire.db
A strace on /usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test
shows the following output:
mkdir("/var/mail/root", 0770) = -1 EEXIST (File exists) stat64("/var/mail/root/Trash/dbox-Mails", 0xbfda2708) = -1 ENOENT (No such file or directory) write(2, "Info: stef/Trash: no messages lef"..., 35Info: stef/Trash: no messages left ) = 35
which explains why nothing happens (stat64("/var/mail/root/Trash/dbox-Mails", which is empty, it should not even exist, but it passes by a mkdir), but why does it want to check /var/mail/root and not /var/mail/%u (i.e. why no stat64(/var/mail/stef/Trash/dbox-Mails))?
Thanks for your help and kind regards,

It doesn't go by the email date, it goes by the date/time the email was moved into that folder.
In other words, it won't effect emails that were *already* *in* the folder.
Personally, I'd love to see the tool have an option to go by the email date/time instead of when it was moved into the folder...

!? This isn't what you said when this was discussed earlier earlier:
Was expire plugin enabled then? If it wasn't, it didn't add them to its database so it doesn't know about them.
... has this changed? Or am I seriosuly misunderstanding what you said? Or... you said 'the mailbox'... does this apply only to mbox files, or to maildirs too? Thanks for the clarification Timo... -- Best regards, Charles

I thought I said it several times i several different ways and added a sentence about it to wiki too.. Expire plugin doesn't track each message individually. It only keeps a track of records: <mailbox name> <next timestamp when to look into this mailbox> When the timestamp is reached, it opens the mailbox and expunges all the messages that have old enough save-date.
I'm not sure what above you think contradicts anything I said..

Possibly :)

Expire plugin works the same way with both.

It doesn't, I'm just dense... ;) Thx... And incidentally, I don't see how you can be so patient... my hat's off to you... :) -- Best regards, Charles
Hello,
I know how the expire plugin (should) work. I am actually happy that the expire-plugin works as is is defined.
However, the plugin does not work.
- the folder /var/mail/root is created (empty) for no reason (root mails should be forwarded to me, stef)
- the mails in /var/mail/stef/Spam and/or /var/mail/stef/Trash are not expunged after the determined time
As written in my original mail, I did a strace. In the strace, I see
that expire-tool 'reads' /var/mail/root and 'reports' that
/var/mail/stef has no e-mails.
So, I see two options:
- I made a configuration error (but I don't see it, and I did some serious looking via google and on the wiki, but maybe it's so obvious I didn't pay attention)
- there is a bug in expire-tool
I wrote this e-mail because I suspect the latter [but please inform me if it's the first]
Thanks for your consideration
Stef

This doesn't work with expire-tool, because the way
A strace on
/usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test
works is that dovecot binary first reads dovecot.conf and expands all %u to root. Then it executes expire-tool, which no longer sees %u at all there. The only way to get this working is to have userdb return the path. So:
a) mail_location = dbox:~/ and have userdb return home.
b) Have userdb return mail=dbox:/var/mail/<username>
userdb: driver: passwd
You should be able to do either of those with something like:
userdb passwd { args = mail=dbox:/var/mail/%u }
v2.0 fixes this problem properly.

I tried both mail_location = dbox:~/
userdb passwd { args = mail=dbox:/var/mail/%u }
and
mail_location = dbox:~/
userdb passwd { args = home=/var/mail/%u mail=dbox:/var/mail/%u }
... but both seem to prefer delivering my e-mail in ~

I did restart the dovecot daemon after each configuration change, but I didn't restart postfix, did I have to?

Oh, so it's only deliver that's broken. I guess you aren't giving -d parameter to deliver so it's not doing a userdb lookup. But there's no need to add it, just keep what you had originally:
mail_location = dbox:/var/mail/%u
expire-tool (and imap, pop3, etc.) will just override it from the mail returned by userdb lookup.

Hello Timo,
This works. Thanks for your investigation and time.
deliver uses mail_location = dbox:/var/mail/%u -- my e-mail gets delivered correctly
and all the other compontents use the path from userdb. I used "args = home=/var/home/%u mail=dbox:/var/mail/%u" -- and my e-mail gets expired correctly, too
Kind regards,
Stef
